'What is Good' in the Bible

O vipers' brood, how can you speak what is good when you are evil? For it is from the overflow of the heart that the mouth speaks.

"Why do you ask me," He replied, "about what is good? There is only One who is truly good. But if you desire to enter into Life, keep the Commandments."

A good man from the good stored up in his heart brings out what is good; and an evil man from the evil stored up brings out what is evil; for from the overflow of his heart his mouth speaks.

whereas glory, honour and peace will be given to every one who does what is good and right--to the Jew first and then to the Gentile.

Your fidelity to the truth is everywhere known. I rejoice over you, therefore, but I wish you to be wise as to what is good, and simple-minded as to what is evil.
